* [MIPS] SMTC: Instant IPI replay.Ralf Baechle2007-01-232-21/+47
| | | | | | | | | | | | SMTC pseudo-interrupts between TCs are deferred and queued if the target TC is interrupt-inhibited (IXMT). In the first SMTC prototypes, these queued IPIs were serviced on return to user mode, or on entry into the kernel idle loop. The INSTANT_REPLAY option dispatches them as part of local_irq_restore() processing, which adds runtime overhead (hence the option to turn it off), but ensures that IPIs are handled promptly even under heavy I/O interrupt load.

Since __cpuinit would map to __init with this kind of a configuration, we get a .text refering .init.data warning. This patch solves the problem by converting all of __cpu_up, _cpu_up and cpu_up from __devinit to __cpuinit. The approach is justified since the callers of cpu_up are either dependent on CONFIG_HOTPLUG_CPU or are of __init type. Thus when CONFIG_HOTPLUG_CPU=y, all these cpu up functions would land up in .text section, and when CONFIG_HOTPLUG_CPU=n, all these functions would land up in .init section. Tested on a i386 SMP machine running linux-2.6.20-rc3-mm1.

* [MIPS] Alchemy: Fix PCI-memory accessAlexander Bigga2007-01-101-4/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | The problem was introduced in 2.6.18.3 with the casting of some 36bit-defines (PCI memory) in au1000.h to resource_size_t which may be u32 or u64 depending on the experimental CONFIG_RESOURCES_64BIT. With unset CONFIG_RESOURCES_64BIT, the pci-memory cannot be accessed because the ioremap in arch/mips/au1000/common/pci.c already used the truncated addresses. With set CONFIG_RESOURCES_64BIT, things get even worse, because PCI-scan aborts, due to resource conflict: request_resource() in arch/mips/pci/pci.c fails because the maximum iomem-address is 0xffffffff (32bit) but the pci-memory-start-address is 0x440000000 (36bit). To get pci working again, I propose the following patch: 1. remove the resource_size_t-casting from au1000.h again 2. make the casting in arch/mips/au1000/common/pci.c (it's allowed and necessary here. The 36bit-handling will be done in __fixup_bigphys_addr). With this patch pci works again like in 2.6.18.2, the gcc-compile warnings in pci.c are gone and it doesn't depend on CONFIG_EXPERIMENTAL.

* [MIPS] pnx8550: Fix write_config_byte() PCI config space accessorDavy Chan2007-01-081-1/+1
| | | | | | | | | | | | | | | | There's a serious typo in the function: arch/mips/pci/ops-pnx8550.c:write_config_byte() The parameter passed to the function config_access() is PCI_CMD_CONFIG_READ instead of PCI_CMD_CONFIG_WRITE. This renders any attempts to write a single byte to the PCI configuration registers useless. This problem does not exist for write_config_word() nor write_config_dword().

* [MIPS] Discard .exit.text and .exit.data at runtime.Ralf Baechle2006-12-121-2/+4
| | | | | | | | | | | | | | | | | | | | | While the recent cset 86384d544157db23879064cde36061cdcafc6794 did improve things it didn't resolve all the problems. So bite the bullet and discard .exit.text and .exit.data at runtime. Which of course sucks because it bloats binaries with code that will never ever be used but it's the only thing that will work reliable as demonstrated by the function sd_major() in drivers/scsi/sd.c. Gcc may compile sd_major() using a jump table which it will put into .rodata. If it also inlines sd_major's function body into exit_sd() which gcc > 3.4.x does. If CONFIG_BLK_DEV_SD has been set to y we would like ld to discard exit_sd's code at link time. However sd_major happens to contain a switch statement which gcc will compile using a jump table in .rodata on the architectures I checked. So, when ld later discards .exit.text only the jump table in .rodata with its stale references to the discard .exit.text will be left which any no antique ld will honor with a link error.

* [PATCH] fdtable: Make fdarray and fdsets equal in sizeVadim Lobanov2006-12-101-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | Currently, each fdtable supports three dynamically-sized arrays of data: the fdarray and two fdsets. The code allows the number of fds supported by the fdarray (fdtable->max_fds) to differ from the number of fds supported by each of the fdsets (fdtable->max_fdset). In practice, it is wasteful for these two sizes to differ: whenever we hit a limit on the smaller-capacity structure, we will reallocate the entire fdtable and all the dynamic arrays within it, so any delta in the memory used by the larger-capacity structure will never be touched at all. Rather than hogging this excess, we shouldn't even allocate it in the first place, and keep the capacities of the fdarray and the fdsets equal. This patch removes fdtable->max_fdset. As an added bonus, most of the supporting code becomes simpler.

They treat negative numbers as unsigned. When not dealing with a constant, they fall back to using fls() which permits them to use arch-specific log calculation instructions - such as BSR on x86/x86_64 or SCAN on FRV - if available.

| * [MIPS] *-berr: Header inclusions for DEC bus error handlersMaciej W. Rozycki2006-12-062-0/+3
| | | | | | | | | | | | | | | | A fixup to add missing header inclusions for bus error handlers for DECstation system after the recent switch to get_irq_regs(). Signed-off-by: Maciej W. Rozycki <macro@linux-mips.org> Signed-off-by: Ralf Baechle <ralf@linux-mips.org>
| * [MIPS] Compile __do_IRQ() when really neededFranck Bui-Huu2006-12-0623-231/+14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | __do_IRQ() is needed only by irq handlers that can't use default handlers defined in kernel/irq/chip.c. For others platforms there's no need to compile this function since it won't be used. For those platforms this patch defines GENERIC_HARDIRQS_NO__DO_IRQ symbol which is used exactly for this purpose. Futhermore for platforms which do not use __do_IRQ(), end() method which is part of the 'irq_chip' structure is not used. This patch simply removes this method in this case.

* | WorkQueue: Fix up arch-specific work items where possibleDavid Howells2006-12-051-2/+2
|/ | | | | | | | | | Fix up arch-specific work items where possible to use the new work_struct and delayed_work structs. Three places that enqueue bits of their stack and then return have been marked with #error as this is not permitted. Signed-Off-By: David Howells <dhowells@redhat.com>
* [MIPS] Cleanup memory barriers for weakly ordered systems.Ralf Baechle2006-12-042-3/+7
| | | | | | | Also the R4000 / R4600 LL/SC instructions imply a sync so no explicit sync needed. Signed-off-by: Ralf Baechle <ralf@linux-mips.org>
